This work presents a chitosan based resorbable biostrip for label-free electrochemical detection of dopamine (DA).The biostrip consists of mesoporous-chitosan-graphene oxide (m-Chit-GO) composite-based sensing electrode and graphene-based interconnects. Obtained with particulate leaching, the m-chit-GO showed average pore size of 1μmwith slow (2 h) curing process. The response of DA on m-Chit-GO was investigated and compared with their bulk counterpart to study the effect of mesoporosity on voltammogram output signals. The voltammetric investigations were performed with three-electrode set-up using m-Chit-GO electrode as working electrode whereas Ag/AgCl and Graphene were used as a reference and counter electrodes, respectively. The quantitative analysis of concentration-dependent voltammetric peak-current enhancement revealed significantly higher response for m-Chit-GO (10pM) as compared to their bulk state (100 nM) on DA. The presented resorbable biostrip offers a limit of detection of 10pM and thereby shows great promise for detection of DA levels for early diagnosis of neurodegenerative diseases.
